You have developed traits similar to those possessed by yetis, granting you the following benefits:

• Increase Strength or Constitution by 1, to a maximum of 20.
• You gain fluency in Yeti.
• You have advantage on Wisdom (Perception) checks that rely on smell.
• You have advantage on Dexterity (Stealth) checks made to hide in snowy terrain.
• When you finish a long rest, you can choose to give your self vulnerability to fire damage in exchange for immunity to cold damage, for 24 hours.
• As an action, you can choose one creature that you can see within 30 feet of you. If the target can see you, the target must succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) against this magic or take 3d6 cold damage and then be paralyzed for 1 minute, unless it is immune to cold damage. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once you use this feature, you can't use it again until you finish a short or long rest. When you reach 11th level, you can use this feature twice before a rest.
